Okay, before I actually comment on anything, this is the comic for 02-22-2022, and I just think that's neat.
If you want to write that 2022-02-22, that is also neat. The point is there's a lot of 2.
Also, I like overly-optimistic smiling Grace with her hands on her hips, and am certain she will return many times in the future.
ANYWAY!
I had trouble writing this comic, and that was in large part because I was trying to write more than it needed to be. Beyond establishing the Theory of Nanase Relativity, the point of them walking together was a friendly interaction that Grace was happy with, and Camelia clearly having developed some fondness for Grace.
Like, that's it.
Would you believe I sometimes overthink things?
As for Grace being there for a while, I imagined the nurse having several questions and tests to make sure Grace was okay. Looking it up, there's a lot to check for, tests that can be done, and it just generally sounded like a good idea to keep an eye on her for a bit.
That being my understanding, and working under the assumption that this nurse was good at their job, Grace being there for a while seemed right.
Granted, my understanding could well be completely incorrect. I am not a nurse, a doctor, or even a quack. So maybe I just characterized them as overly protective, or not diligent enough? I dunno. I'm sure people will let me know in any case.
